A complex type that specifies a list of Lambda functions associations
for a cache behavior.

If you want to invoke one or more Lambda functions triggered by
requests that match the PathPattern of the cache behavior, specify
the applicable values for Quantity and Items. Note that there can
be up to 4 LambdaFunctionAssociation items in this list (one for
each possible value of EventType) and each EventType can be
associated with the Lambda function only once.

If you don't want to invoke any Lambda functions for the requests
that match PathPattern, specify 0 for Quantity and omit Items.
